“…Other studies also showed that supplementation of choline or BET increased ADG of birds fed diets marginally deficient in Met [19][20] . Furthermore, betaine is an osmolyte that could improve intestinal structure and function to increase growth performance [21,22] . It appears, thus, that BET and Met in marginally Metdeficient diets could lead to an equivalent growth response in broilers and that BET could spare a small portion of the Met.…”

Problem Statement: The efficacy of Methionine (Met) sparing effect of Betaine (BET) has been shown to be associated with dietary compositions, animal physiological stage and living conditions. This study was to determine the extent to which dietary Met could be replaced by BET in broiler chickens under the feeding conditions specific to Chinese poultry industry.Approach: A total of 900 day-old Arbor Acres broiler chicks were fed three corn-soybean meal-based starter rations (d 1-21) and grower rations (d 22-42) for a total of 42 days. Met levels in the diets were: Diet 1, Met content at the recommended level (Control); diet 2, Met level at 85% of the Control supplemented with BET at the level of 400 (starter) or 300 (grower) mg kg^-1 DM; Diet 3, Met level at 75% of the Control supplemented with BET at the level of 600 (starter) or 500 (grower) mg khg^-1 DM. The broilers were raised in a temperature controlled house with 3 pens (replicates) per dietary treatment. Results: In general, treatment had no effect on body weight, feed intake or feed efficiency. Concentrations of growth hormone and insulin-like growth factor-1 in the serum of broilers fed Diet 3 were higher (p<0.05) than that of broilers of other treatments. Supplementation of BET at the level of replacing 25% of total Met increased (p<0.05) breast meat yield and protein content of breast meat and liver, but decreased (p<0.05) abdominal fat yield and ether extract content of liver. Conclusions/Recommendations: Supplementation of BET to replace up to 25% of total dietary Met did not affect the growth performance but improved the carcass quality of the broilers. BET could be used to spare 25% of the total Met in broiler diet that was formulated based on the Feeding Standard of China

Abstract. This trial was conducted to examine the effect of betaine on performance, humoral immunity, small intestinal morphology and blood osmotic pressure parameters of broiler chicks consumed different levels of water salinity. Total of 520 day-old broiler chicks (Ross 308) were used with 2×4 factorial arrangement in completely randomized design. Experimental treatments were consisting of 2 levels of betaine supplementation (0 and 1.5 g/kg) and 4 levels of total dissolved solids (TDS) (250, 1 500, 3 000, 4 500 ppm). In this trial daily feed intake (DFI), daily weight gain (DWG) and feed conversion ratio (FCR) were recorded on days 14, 28 and 48. Small intestinal morphology was evaluated at the age of 28. Humoral immunity was assessed by evaluation of antibody titre against sheep red blood cells (SRBC) and also Newcastle and influenza antigens. At the end of the experiment, blood was taken and concentration of plasma Na, K, Cl and haematocrit blood percentage was determined. Results showed that DWG significantly decreased and FCR increased in 4 500 ppm of water TDS in growing, finishing and whole period of broilers production (P<0.05). Furthermore increased plasma Na and blood hematocrit percentage observed in 4 500 ppm of water salinity (P<0.05). Betaine significantly increased DFI during growing phase (P<0.05). Betaine supplementation substantially increased antibody titre against influenza and also bursa of fabricius relative weight (P<0.05). Additionally, betaine inclusion increased villi height in ileum (P<0.05). In conclusion, increasing trend of water TDS affect chickens performance and betaine supplementation is able to improve antibody titre against influenza.

“…However, saline water decreased the forequarter weight and the weights of non-edible and edible organs, but the hot carcass weight and dressing percentage were not affected by water salinity. Moreover, Honarbakhsh et al (2007) showed that saline water (1,000 and 2,000 mg TDS/l ) improved the breast yield (P<0.01) of broiler chicks, but slightly decreased the abdominal fat and sartorial percentages compared with fresh water group On the contrary, many studies reported that saline water did not influence carcass traits. Such as, Walker et al (1971) found that the carcass weight was not affected in Merino wethers consuming saline or tap water.…”

Limited freshwater resources and climatic change are major challenge face animal production industry, especially in the arid and semiarid regions. Climate changes are reflected in global warming and rainfall reduction, which in turn may increase the salinity of both soil and water. Within the reclamation strategy, groundwater will be the main source of used water in cultivated desert lands in Egypt. However, the groundwater has high salinity and the cost of desalination is expensive. This review gives an overview of the impact of using saline water as an alternative source of fresh water to avoid water scarcity effect on the performance, carcass traits, and meat quality of farm animals. The ability of animals to tolerate saline water depends on the animal species, salinity level and the type of salt minerals in water. Some studies indicated that the animals' performance improved in low levels of salinity, but the performance decreased when the salinity levels was increased. In conclusion, this study implies that the saline water containing high concentrations of minerals mainly sodium chloride can largely affect the livestock productive aspects.
